Cannot use get_wch, linking error

I was dveloping an app and it worked fine, but when I tried to use get_wch() it blew up.
This is an example that fails:
extern crate ncurses;
use ncurses::*;
fn main() {
let mut search_string = String::new();
loop {
let user_input = get_wch();
match user_input.unwrap() {
WchResult::Char(27u32) => break,
WchResult::Char(ch) => {
search_string += &std::char::from_u32(ch).unwrap().to_string();
},
_ => {}
}
}
}
This is the error message:
alex@smartalex-bed:~/.repos/codelib/rust/ncurses_issue$ cargo run
Compiling ncurses_issue v0.1.0 (/home/alex/.repos/codelib/rust/ncurses_issue)

I tried to do sudo apt install ncurses*, but the same error happens again. I'm using XUbuntu 18.04.4 LTS (Bionic Beaver).
What could be the issue?
